Specification of Letters Patent.

Patented July 6, 1915.

Application filed 'lsebruary 19, 1915. Serial No. 9,270.

To all whom it may concern Be it known that I, CARL RUDOLPH SoHUL'rz, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Bottle-Cap, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has is view are: to provide means for reinforcing the body of a bottle adjacent the neck portion thereof; to provide an inscription plate and means for holding the same rigidly in position on the body of a bottle; and to provide a light metal cover for protecting a bottle structure adjacent the neck thereof.

Drawings-Figure 1 is a side view of a bottle having a cap attached thereto constructed and arranged in accordance with the present invention, a portion of said cap being shown in section to disclose the interior structure thereof; Fig. 2 is a perspective view in detail, of a cover plate for protecting the weaker portion of the bottle structure; Fig. 3 is a detailview showing a contracting ring for anchoring the covering plate in service position.

Descriptz'0n.-As seen in the drawings, the bottle 8 is of conventional pattern, and is provided with a lip 9. For surrounding the neck of the bottle, and below the lip 9, a split, screw-threaded collar 10 is provided. The collar 10 is divided to form a space between the end walls 1'1. Below the screwthreaded portion of the collar 10, said collar is extended to form an annular lip 12, the inner surface of which is recessed to form a curved wall 13, which corresponds with the neck 14 of a cover plate 15. The cover plate 15 is cupped to provide an inclined wall terminating at the outer edge thereof in an annular cylindrical wall 16. The plate 15 is made preferably from light metal. The form to which it is pressed gives sufficient strength to the cover to preventthe same becoming marred in service, and to provide a protective member extending over an enlarged area of the bottle structure to distribute any strain or shock on the neck of the bottle, imparted thereto when the collar 10 or dispensing device, such as the draw-0E cock 17 connected therewith, is struck. The

grip the same; and means for exposed surface of the cover may be utilized for having imparted thereto any suitable inscription or ornamentation directing the consumer as to the disposition of the bottle, or to augment the pleasing appearance thereof. v

The cook 17 or other dispensing member with which bottles of this character are provided, has a threaded cap nut portion 18. The portion 18 is slightly tapered inward, so that when screwed upon the collar 10, said collar is gradually compressed or reduced in diameter and forced upon the neck of the bottle and the neck 14 of the cover plate 15 which is infolded by said collar 10 and the lip 12 thereof. When the cook 17 is screwed firmly upon the collar 10, it will be found, the curved inner surface of the lip 12 grips the neck 14 and presses down the plate 15 to rest firmly on the bottle 8. When, now, any blow or strain is imparted to the cook 17 or fixture connected with the collar 10, it is transferred or distributed to the plate 15 and to the annular wall 16 thereof. The wall 16 being spread to inclose an extended area, the force or impact of the strain is dissipated in proportion to the extent of the area.

Claims:

1. A bottle cap comprising a cover plate having a cup-shaped body provided with a contracted neck and an enlarged annular rim, the wall of said neck being inclined upwardly and inwardly; a contractible collar having a lip for surrounding said neck to contracting said collar in service.

2.

3. A bottle cap comprising a cover plate having a cup-like body embodying a contracted neck opening, the outer walls whereof are inclined, and .a relatively extended, cylindrical bottom rim; a contractible collar having a screw-threaded portion and a bot- In testimony whereof I have signed my tom-opening recess, the inner Walls of said name to this specification in the presence of recess corresponding with the outer Walls two subscribing Witnesses.
